I was to lazy to take a look at the
I'll just give you a short intro to whet your appetite, find all details here yourself.
This is the old way of connecting a signal to a slot. To use the new-style support just replace line 11 with following code
If you need to define your own signal you'll do something like this (off the top of my head):
And the old way:
IMHO the new-style support is more pythonic and you don't have to specify your signals as strings when connecting. If you use pydev (eclipse) you'll also have completion support for signals.
Today, we're going to discuss the Python/Qt way of allowing your application to respond to user-triggered events: signals and slots. When a user takes an action — clicking on a button, selecting a value in a combo box, typing in a text box — the widget in question emits a signal. Because you have connected textActivated (signal) with lineEdit.setText (slot), so, if you set the currentText for object when it is emitted, the setText catch the object.If you connect the signal to three lineedit.setText, all of the lineedits set text by the same information. For instance, one event activates its slot and related subsequent events trigger another signal and the code in its slot to be executed. General understanding of the python programming language. No prior knowledge of QT is required. Connecting signals and slots. We use the QObject.connect method to connect signals and slots.

signal and slot support which was introduced in PyQt 4.5 until yesterday. I did know that there were something called new-style signals and slots but that was the end of the story. Now I have taken the time and I think it's a cleaner solution than the old-style.I'll just give you a short intro to whet your appetite, find all details here yourself.

Thenew-style support introduces an attribute with the same name as the signal, in this case clicked.
